Eye detection is a popular and useful operation in OpenCV.
It can be used in a variety of applications including face recognition systems and driver fatigue detection.
This process use Haar cascades machine learning technique.
We can also use self trained models in this process.
In this tutorial, we’ll learn about eye detection with OpenCV.
Input:
Code:
import cv2
input_image = cv2.imread('gg.jpg')
eyeCascade = cv2.CascadeClassifier(cv2.data.haarcascades + "haarcascade_eye_tree_eyeglasses.xml")
gray = cv2.cvtColor(input_image, cv2.COLOR_BGR2GRAY)
eye = eyeCascade.detectMultiScale(gray)
for (x, y, w, h) in eye:
img = cv2.rectangle(input_image, (x, y), (x + w, y + h), (0, 0, 255), 2)
cv2.imshow('Detected eyes', input_image)
cv2.waitKey(0)
First we imported cv2 and used cv2.imread function to read the image.
The next line loads the pre-trained eye detection classifier.
Then, we used cv2.cvtcolor() function to convert input image into grayscale.
Then, we used eyeCascade.detectMultiScale() function to detect all the eyes in image.
Then, we used a for loop to draw a rectangle around the detected eyes.
At last, we used imshow() function to display the final result.
